World of Digital Libraries

Identified Problems:

Interoperability

Format translation

Multiple data formats in DL:

How to support them?

How to translate between them?

Who should create mappings?

Real-life problems – user’s expectations Searching: Effective and Accurate We want correct and fast answers!! Intuitive and Simple Asking questions should be easy. Meaning Jaguar – a car or an animal? Reasoning Give me articles written by students of X in Galway? Identified problems: Intuitive interface for asking complex querries

Searching:

MarcOnt Initiative Motivation: Build a bibliographic ontology for the Jerome Digital Library MarcOnt Initiative goals: Deliver a set of tools for collaborative ontology development Collaboration Tools for domain experts Enable mediation between formats (MMS)

Motivation:

Build a bibliographic ontology for

the Jerome Digital Library

MarcOnt Initiative goals:

Deliver a set of tools for

collaborative ontology

Tools for domain experts

Enable mediation between formats (MMS)

MarcOnt Ontology Central point of MarcOnt Initiative Translation and mediation format Continuous collaborative ontology improvement Knowledge from the domain experts Community influence and evaluation

Central point of MarcOnt Initiative

Translation and mediation format

Continuous collaborative ontology improvement

Knowledge from the domain experts

Community influence and evaluation

MarcOnt Ontology Goals: Capture concepts from the legacy bibliographic formats MARC21, Bibtex, Dublin Core Lattes, ... Create a uniform bibliographic description format for digital libraries. Enable the use of Semantic Web technologies (eg. reasoning) to improve capabilities of digital libraries Improve interoperability

Goals:

Capture concepts from the legacy bibliographic formats
